面向可持续城市生态系统管理的资源环境承载力评价方法与实践应用——以烟台市为例

全面科学的资源环境承载力评价是国土空间规划编制的前提。面向可持续生态系统管理视角,提出了由“潜在”和“现实”资源环境承载力构成的资源环境承载力评价框架和理论模型,并以烟台为案例进行应用,分析了“潜在”和“现实”资源环境承载指数的相互关系。结果表明：（1）烟台市“潜在”资源环境承载指数总体偏高,“现实”资源环境承载指数总体中等,各区（县）空间差异较大。（2）水资源短缺与环境污染问题是未来影响烟台市可持续发展的瓶颈,资源环境禀赋的限制和经济发展对城市生态系统服务弱供给区域影响较大,对“潜在”资源环境承载指数的影响在城市边缘区域较大。（3）所提出的评价逻辑框架和理论模型应用效果良好,丰富和完善了资源环境承载力评价理论方法。

Evaluation method and application for resources-environment carrying capacity towards sustainable urban ecosystem management: A case study of Yantai city

Scientific cognition and evaluation on resources-environment carrying capacity is the basis and prerequisite for territorial spatial planning. From the perspective of sustainable urban ecosystem management, the evaluation framework and theoretical model for resources-environment carrying capacity and indices of "potential" (RECC_p) and "realistic" (RECC) resources-environment carrying capacity were proposed. Taking Yantai city as an example, we use the trade-off coefficient method to discuss the relationship between RECC_p and RECC. Results showed that the RECC_p was overall high while RECC was medium in Yantai city. There were significant regional differences between districts (counties). The shortage of water resources and environmental pollution were bottlenecks that would restrict the sustainable development of urban ecosystem in the future. The impacts of human activities on RECC in areas with low supply of ecosystem services were more obvious than those in areas with high supply. The impacts of human activities on RECC_p were significant in urban fringe areas. This research could enrich the theoretical methods for evaluation of resources-environment carrying capacity and provide decision-making support for land use optimization.
